Hello, there is a misunderstood.

The options available in the "editing properties" dialog (toc - right click on layer) let the user decide the type of snapping, but the snapping itself is enabled with in the main menu: Edit > Enable-disable snapping.

You can do this test (follow the steps exactly):

- close gvSIG if it is running
- delete the folder /home/<user>/gvSIG to make sure that snapping settings are the ones by default (just to simplify the test)
- start gvSIG
- create view and add shapefile
- start editing
- do a "zoom-in" somewhere in the layer (this is important)
- now the snapping works

If you click on " Edit > Enable-disable snapping" then the snapping in disabled/enabled.

IMPORTANT COMMENT:

The spatial index used by the snapping mechanism only works if the view is moved AFTER starting the editing mode. This is because geometries are added when they are painted (and only if the layer is in editing mode). That's why the user needs to move the view before using the snapping (after starting editing). I don't know if this is the desired behavior. Perhaps when editing starts we can force a repaint or we can ask the user if the geometries in the current view must be cached.

Hi.

I think it is important that the snapping is available just after start editing (no need to do a zoom) because is quite common that the user prepares the zoom level to work before start editing. I mean:

1. Load the layer.
2. Do zoom over the geometries I want to edit.
3. Start editing
4. Use an edit tool.

Unless it is complicated for some technical reason I propose to fix this undesirable behavior.

Manuel.
